SERVICE-BOX FOR GAS AND WATER PIPES SPECIFICATION forming part of Letters Patent No. 230,704, dated August 3, 1880,

Application filed February 11, 1880.

.To all whom it may concern:

Be it known that I, FRIDERICH JAREGKI,

a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Service-Boxes for Gas and Water Pipes 5 and I do hereby declare the following the same, reference being had to the accompanying drawings, and to letters or figures of 1 reference marked thereon, which form a part of this specification.

My invention consists in providing certain improvements in the construction of iron extension service-boxes for gas and water pipes, and is an improvement on the device patented to me August 22, 1876, No. 181,349, as will appear in the following general description.

My device is shown in the accompanying drawings, as follows: v

Figure 1 is an elevation view. Fig. 2 is a longitudinal section on the line m a: in Fig. l, with the small section removed, afragment of which is shown in elevation as in position to enter the large section. Fig. 4 is a section similar to Fig. 2, but shows the side removed in Fig. 2. Fig. 3 is a transverse section of the larger sectionof the box 011 the line 3 y in Fig. 4. Fig. 5 is a top view of the box, showing the cover or cap.

A A is the large section of the box, and is made of two diameters, as claimed by me in a former patent. B is the extensible partof, the box, and D is the cap or cover. All these parts are made of cast-iron, preferably.

The part A A is provided with a groove, a a a. This groove begins at the bottom of the part A of the part A A, and extends up nearly to the top thence it runs circumferentially part of the way around, more or less, as maybe desired, and is there marked a thence it passes vertically to the top, and is there marked a. This groove is formed in the casting at the time it is cast.

On the telescoping or extensible part B is a lug, Z). (See Fig. 2.) This lug fits in the groove a a a, and the two parts are put together by entering the lug in the groove a,

and when it reaches the circumferential groove a the parts are turned upon each other until the lug can enter the vertical groove a, when the parts B A A are shoved upon each other like the parts of a telescope.

A leaf-spring, c, is adjusted in a notch on the inner side of the part A A, so as to press against the part B with sufficient force to hold it at any point of extension. This spring is shown-in Figs. 3 and 4.

The cover D is pivoted to the part B, and opens by swinging around, as shown in Fig. 5. It is secured shut by a screw, E, which passes through the cap and enters a lug, E, on the part B. Where the screw E passes through the cap 1) it (the'cap) is made thicker, as at D, and the flange B of the part Bis cut away, as at d, to allow this extra thickness orlug D to come in place over the lug E.

Each of the parts has the form shown as it leaves the mold, no work being required except to drill the pivot-holes in the cap D and flange B, and the holes for the screw E, and cut the threads therein. The extensible section B may be of wrought-iron.

Ido not claim an extensible box as new, for it is shown in the former patent referred to; nor do I claim, in an extensible service-box, a notched slot in one part and a lug on the other part operating in said slot, for such a contrivance is old, and is faulty in that when extended the said slot forms an opening through which dirt will enter the box.

My invention, as regards the groove above described, consists, first, in the fact that it is .in effect the same as a slot, but it is closed, so

as to exclude dirt, and is formed in the casting when cast; second, in the form or direction of said groove.

[t is not essential that the groove a a a be constructed exactly as shown, for the groove a may extend directly to the top, and the circumferential .groove may be dispensed with; but this groove is advantageous, as, when the box is extended so as to allow the lug b to rest in that groove, the parts are not liable to settle together, as when the spring c is depended upon to keep them extended; and the groove a may be provided with a series of notches on one side, into which the lug I) can be set by turning the part B, so as to retain the parts at various degrees of extension. This I latter construction would obviate the necessity of the spring 0, although it would still be useful in preventing the parts turning upon each other too easily.

The notches I have spoken of would be, in effect, short circumferential grooves like a.

In the former patent to me, above referred to, I employ a spring for the same purpose as the one above described.

The presentinvention. as regards said spring, consists wholly in a change of form of spring and the manner of applying the same, the present method of application being much simpler and cheaper.

I am also aware that lateral and circumferential grooves have been cast in pipes for the purpose of forming a coupling-as, for example, in hose-couplings. Ido not, therefore, intend to claim, broadly, such a method of attachin g one pipe-section. to another; but in the case just referred to no adjustment is possible at various degrees of extension as is the case in my device above described, where said capability is the object and purpose of the invention.

What I claim as new is- 1. In an extension service-box for gas ant water pipes, the combination, substantially as described, ofthe following elements: two tnbesections of unequal diameter, so as to permit one section to telescope within the other, one of which sections is provided with a groove and a binding-spring, and the other with a lug to fit in said groove.

2. In an extension service-box for gas and water pipes, the combination, substantially as herein set forth, of the following elements: two tubesections, one of which is sufficiently larger than the other to permit said sections telescoping upon each other, one of which tube-sections is provided with two vertical grooves and ahorizon tal circumferential groove connecting the two vertical grooves and a binding-spring, and the other tube-section is provided with a lug to fit in said grooves.

3. The combination, with the upper section of an extensible service-box for gas andwater pipes, of a flange, B, and lug E thereon, and a cover, D, pivoted on said flange, and provided with a screw, E, to engage with said lug E, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
